Sébastien Érard – the founder of the Érard brand, was an unusually gifted and hard working piano and harp maker, also known as a master organ repairer. He was a founder of 23 piano making patents. The most important one of them is a double action harp and piano with double repetition action. He worked and lived in Paris and London, but he was born in Strasbourg.
Even though he paid more attention to harps, his pianos are still impressive in their appearance, touch and tone.
